FEED-WATER H EATER. I

SPECIFICATION forming'part of Letters Patent No. 367,839, dated August 9, 1887.

Application filed Aprilll, 1857. Serial No. 234,364.. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM L. OAKEs, of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and use- :ful Improvements in Feed-Tater Heaters and I uritiers, of which the following is a specificaion. y

The object of my invention is to increasethe effectiveness of feed-water heaters both generally and specifically; and I attain my object by means of the combinations, sub-combinations, details of construction, and relative arrangements of parts, fhereinafter set forth in detail, and specifically claimed.

In the drawings accompanying and forming a part of this specification, Figure 1 is a Ycentral vertical section of my device, and Fig. 2 is a horizontal section on dotted line win Fig. l.

The casing-cylinder A is divided in three compartments-namely, steamchamber B, settling-chamber C, and hot chamber D. The settling-chamber is at thelower portion of the cylinder and has a dished bottom, in, from the lowest surface of which the blow-oft' pipe n extends. thug-chamber and contains the vertical waterpipes a, which connect the settling-chamber with the hot chamber. The hot chamber is above thesteamchamber, and is formed of a basin, g, detached, except at its upper rim, from the casingcylinder. Exhaust-steam is admitted to the steam-chamber through vcrtical pipe c, which extends through the center of the settling-chamber and terminates near the longtudinalcenter of the steam-chamber. The escape-pipe d for the exhaust-steam extends downward from the lowest portion of the steam-chamber and encompasses the feedpipe c. y

Water is conducted to the settling-chamber through pipe z', passes throughpipes a to the hot chamber, and is ultimately discharged through pipe b, which extends downward through thefexhanst'steam feed-pipe c, and connectsl with the boiler inany suitable manner. The cap s of the hot chamber is 'internall y concaved and externally recessed, and is provided at its center with an opening with which safety-valvep and dischargevalve g are connected. Plate f a combines with the recessed cap to form space f, which is intended to lessen the radiation of heat, and which may The steamchamber is above the setbe lled with any suitable non-conductor, atmospheric air being preferred.

The hand-hole r provides ready access to the settling-chamber. Valve o regulates the discharge of blow-off pipe n. Check-valve Z and stop-valve 7a provide means for effectually controlling the supply of water. Lower head, e, of the steam-chamber forms a basin for the collection and immediate discharge of water condensed from the exhaust. Upper head,f, forms the bottom for the hot chamber. The exhaust-pipes c and d terminate in a connection-chamber, E, having partition g', separat- Aing the openings c and cl ofthe different pipes, and also having anges h,with which the conducting-pipes connect.

y The Voutlet-pipe cl connects with the upper portion of the connection-chamber. The inlet-pipe c connects with the partition. The connection-chamber is secured to the bottom 0f the settlingechamber by a series of circularly-arranged bolts, which permit the connection-chamber to be rotatingly adjusted. The outletpipes b and d are secured rigidly at their upper ends in their respective bearings and have packing-connections at their lower ends,

, as indicated in the drawings.

In operation, water is first fed to the settlingchamber at the bottom of the cylinder, where the lowest temperature will naturally exist, and is warmed therein to some extent. Passing upward through pi pcs a, more direct contact with the exhaust is had and the temporature is considerably raised. In the hot chamber, which is almost entirely surrounded by the hottest exhaust and protected from radiation, heat is rapidly generated, and the temperature is raised to the ,highest possible degree in the narrow discharge-pipe, vwhich is in direct contact on all sides with exhauststeam fresh' from the steamcylinder.

The discharge cl atthe .bottom of the steamchamber insures the constant discharge of water formed byY condensation of exhaust, which would otherwise haveatendency to cool the lower connections of pipes a and induce leakage by the consequent contraction.

The dischargevalve q provides means for blowing off any scum that may accumulate in the concavity of the cap, and the simplicity of the -internal construction of the settling-cham- IOO bcr and its/ready accessibility through the hand-hole form, with blow-off pipe n, complete provision for the removal of sediment.

The rotative adjustment of the connectionchamber enables connections to be made from any direction relative to the hand-hole and lateral pipes, which is a matter oi' great convenience in setting up heaters in angles, nooks, and other places, where i'ree access to all parts of the heater may not be had.

The packing-joints at the lower ends ol the discharge-pipes provide for independent contraction and expansion therein, such provision being especially desirable for the waterpipe, which, from its length and direct exposure to heat, is apt to become unduly extended while the feeder is in operation.
